--MLBPA
Per Article XX-B of the MLB/MLBPA collective bargaining agreement, any player on an MLB Reserve List who has accrued at least six years of MLB Service Time and who is not signed for the following season becomes a free-agent at 9 AM (Eastern) on the first day after the final game of the World Series. In addition, as for any international player who has accrued service time with a foreign "major league" club or clubs prior to signing a "first contract" with an MLB club, any service time accrued while on the active roster of a foreign club(s) may be considered when determining Article XX-B contractual rights & eligibility.
An Article XX-B MLB free-agent who signs a Major League contract after 11:59 PM (Eastern) on the 5th day after the final game of the World Series receives automatic "no trade" rights that extend through June 15th of the following season, even if the player re-signs with his former club.
If an Article XX-B MLB free-agent signs a minor league contract at least ten days prior to MLB Opening Day, and then is either not released by 12 PM (Eastern) on the 5th day prior to MLB Opening Day or added to an MLB Reserve List (40-man roster) or MLB 60-day Disabled List by 12 PM (Eastern) on MLB Opening Day, the player automatically receives a $100,000 retention bonus, and the player can unilaterally opt-out of the minor league contract on June 1st if he has not been added to an MLB Active List (25-man roster) or an MLB Disabled List by that date.
